Assume that a radiologist group practice has the following cost structure: 1 pts Fixed costs $543,366 Variable cost per procedure $28 Charge (revenue) per procedure $107 Furthermore, assume that the group expects to perform 7,841 procedures in the coming year. Also assume that the practice contracts with one HMO, and the plan proposes a 17 percent discount from charges. What volume is required to provide a pretax profit of $213,159? (Round your answer to 2 decimal places. For example, 12.3456 should be entered as 12.35. REMINDER: quantities are always rounded UP. Canvas does not have this capability.)
